Troubleshooting a GPU Failure: Understanding the Signs and Next Steps

When your computer unexpectedly shuts down and refuses to power on, it can be a frustrating experience, especially if it belongs to a loved one. Recently, my wife’s PC faced such an issue, shutting off randomly and becoming completely unresponsive. After some troubleshooting, I managed to isolate the root of the problem, but I wanted to share my experience and seek advice on confirming a GPU failure.

The Initial Problem

One day, out of the blue, my wife’s PC decided to call it quits. No warning signs, just a complete shutdown. Upon attempting to turn it back on, the power button would light up for a brief moment before everything went dark again. It was as if the system had an internal meltdown.

The Troubleshooting Process

To get to the bottom of this mystery, I started by removing the graphics card—an EVGA GTX 950—and switching to the integrated graphics on the motherboard. To my relief, the system booted up perfectly, indicating that other components, like the motherboard and power supply, were functioning well.

However, upon reconnecting the GPU, the situation reverted to square one; the PC refused to power on again. This led me to believe that the GPU might indeed be the cause of the malfunction.

Investigating the Graphics Card

I conducted a quick visual inspection of the GPU in search of any obvious signs of damage, such as burn marks or swollen capacitors. Unfortunately, I’m not an expert in spotting hardware issues, so this alone wasn’t conclusive. Additionally, I considered other potential culprits, such as a faulty PCI-E slot or a malfunctioning 12V power rail from the PSU, which could also lead to similar symptoms.

Seeking Community Insights

Before declaring the GPU dead, I was eager to explore any further diagnostic steps that could help confirm or dismiss other possible explanations. Engaging with the tech community can be incredibly helpful, and I’m curious to hear from others who may have experienced similar issues or possess expert knowledge in diagnosing hardware failures.

The Final Revelation

In a bid to gather more evidence, I took the GPU and installed it into my stable PC, which is equipped with all known good components. To my dismay, pressing the power button resulted in a catastrophic failure of the GPU—indicating that it was, indeed, fried. Thankfully, my primary system remained intact, but this experience reinforced the importance of thorough troubleshooting when dealing with hardware
